如何在python中使用openpyxl访问列

Question

I am trying to access a column from a workbook. Im able to do it using this:

for cell in sheet1["A"]:
    list.append(cell.value)

However, this collects all the value on the A column. What I need starts from A2 and on. I this code:

for cell in sheet1["A2":"A"]
    list.append(cell.value)

What am I missing here?

Answer 1

A super simple idea to fix your code is to use len() as in the following;

for cell in sheet1['A1':'A'+str(len(sheet['A']))]
    list.append(cell.value)

Remember that str() converts its argument to a string and + between two strings concatenates them. len(sheet['A']) returns the length of the column A.
